उत्तर
The metal that cannot be obtained by the electrolysis of an aqueous solution of its salts is Ca.
Explanation:
Calcium (Ca2+) has a very high reduction potential, so in aqueous solution, water gets reduced to hydrogen gas instead of Ca2+ being reduced to calcium metal. Hence, calcium cannot be obtained by electrolysis of its aqueous salt solution.
